claims. (c1. 57-116) My invention relatesto fliers of the type used with spinning machines and more particularly to an improved flier block arrangement having means for attaching and supporting the flier wires.

One of the objects of the present invention is to provide a ier block structure constructed and arranged to permit use of a single flier wire having arms extending outwardly on the same side of the block. In the use of ier wires of this character, it is necessary to provide means for balancing the block, that is to say, means to compensate the unbalanced forces due to the projection of the flier arms on the same side of the block.

Heretofore it has been suggested to use balancing devices and in application Serial No. 283,- 880, filed September 30, 1939, I have disclosed a balance in the form of a loop adapted for use with a flier block having a metal ier wire supporting plate. Considerable demand has recently developed for a lightweight flier block adapted for use with a single wire arranged so that the horizontal and drop arms extend outwardly on the same side of the block. While in some circumstances the winding operation requires a flier arrangement of this type it is desirable from the standpoint of eiciency and economy to have a block adapted for general application, that is, a block which can also be used with a single wire having arms on opposite sides of the block or with conventional double ilier wires.

After considerable research and experimentation, I have found that the forces developed by the arms on the same side can be balanced or otherwise compensated by attaching a member to the block in a plane above the plane of the arms of the flier wire and extending outwardly therefrom in a direction opposite the arms. The present invention also comprehends the provision of a block structure adapted for use with -conventional arrangements of single and double wires.

An object of my invention is to provide an improved flier block.

Another object of my inventionis to provide a flier block adapted for use with a single flier wire having arms extending outwardly on the same side of the block.

Still another object of my invention is to provide a ier block adapted for use with a single flier wire, a double flier wire or a single wire with arms on the same side of the block.

Yet another object of my invention is to provide an improved ier block-having flier wire balancing lmeans associated therewith.

With these and other objects in view, which may be incident to my improvements, the` invention consists in the parts and combinations to be hereinafter set forthy and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement, withoutV departing `from the spiritY and. scope Yo i the appended claims. f

Inrorder to make my invention more clearly understood, I have shownin the accompanying drawing means for carrying the same intoA practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawing: Figure l is an elevational view, partly in section, showing Ymy improved nier in operative position on a bobbin spindle. n

Fig. 2 is a plan view of the flier block shown in Fig. 1; and

Fig. 3 is a perspective view of the iiier block showing Y a flier wire and balancing member mounted thereon.

Referring to the drawing and more particu-` larly to Fig. 1, there is shown a ier arrangement associated with a bobbin l, mounted in operative position on a suitable spindle 2, of a' conventionalwinding machine. The Ibobbin is provided with a head member 3, and a centrally recessed portion 4, adapted to receive' a ferrule 5, having an aperture 6, through which theier foot is inserted. The ilier block designated gen erally by numeral l, comprises a centrallyV apertured body portion 8,V having a -base portion 9, and head portion lil. Between the base and head portions, in the vicinity of the base, there is provided a peripheral flier wire receiving groove Il, adapted to form a seat for a flier wire. Be-

tween the base of the head portions of the block,

above the flier wire receiving groove, there is also provided a peripheral groove I2, adapted to receive a balancing member, arranged to compensate the unbalanced forces due to the projection of the ier wire arms on the same side of the block.

Referring to Figs. 2 and 3, it will be noted that the flier wire is formed with a central block engaging section i3, which seats in the peripheral groove Il, and that the arms i4 and I5, of the wires are entwined as at I6, in the vicinity of the block. "The wire is thus securelyA attached to the block by twisting the arms so that a fairly tight iit is obtained. In order to prevent relative movement of the flier wire with respect to the block, that is to say, to prevent a rotative movement of the wire on the block, a suitable pin II, is provided. As shown in Fig. 1, flanges I8, I 9 and 20, which deiine the peripheral grooves II and I2, are bored to form concentric openings in the iiange for the reception of pin Il, which in the seated position extends into groove II, between the arms of the wire, acting as a stop to prevent rotation of the iiier wire with respect to the block.

In the use of a single wire, having its arms extending outwardly on the same side of the block, it has been found that the unbalanced forces developed by this arrangement of the wire must be compensated, otherwise uniform tension on the thread during the winding operation cannot be obtained. In order to balance out the undesirable forces, the flier block of the present invention is provided with a balancing member in the form lof a wire loopl adapted to seat in the upper peripheral groove I2, in the vicinity ofthe head portion of theblock.

Aswill be seen in Figs. 2 and 3, the balancing member designated generally by numeral 2|, 'comprises a loop formed from wire, having arms 22, provided with curved portions 23, constructed and arranged to seat in the upper peripheral groove I2. The curved portions V3, terminate in ends 24, adapted to seat in openings 25, formed at diametrically opposite points in the body of the block and in the upper peripheral groove portion.

It will be vunderstood that the flier wire balancing member will be formed from wire of suitable gauge to eiect the requiredbalancing of undesirable forces developed by the iiier wire arms. The arms 22, are spaced apart suiciently to provide tension on the curved portions 23, when these portions are in seated position in groove I2, so that ends 24, will be maintained within the recesses 25. By means of this arrangement, the balancing member is securely held vin xed position on the block and undesirable fiexing of the member is prevented.

Referring to Fig. 3, it will be noted that the base portion of the flier block is formed with an eccentric foot 26, which isadapted for insertion into the aperture 6, formed in the ferrule (Fig. l), whereby, the block is maintained in operative position with respect to the bobbin, during the windingoperation,

In assembling the iiier, the flier wire is applied to peripheral groove II, with yits central block engaging section I3, in seated position therein, the arms I4 and I5, of the wire being thereeafterwardstwisted to provide a tight seat between the looped portion of the wire and its Contact portion with the body of the block and pin Il, thus locking the wire and preventing its rotation with respect to the block. The wire balancing member 2|, is then applied to the block by spreading arms 22, a suii'icient distance to per mit insertion of ends `2II in openings 25, and upon release, the curved portions 23, seat in the upper peripheral groove I2.

It will be appreciated that the flier block ofthe present invention is ofgeneral application, that is to say, it may be used with single or double wires of the conventional type, or in certain cir'- cumstances requiring the use of a wire'having arms on the same side of the block, vthe balancing arrangement may be used.

While I have shown and described the pre`` ferred embodiment of my invention, I wish it to be understood that I do not conne myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.
